-  PCP private key structure. Most fields are self explanatory.
-  Some notes:
-
-  'encrypted' contains the encrypted secret key. If it's set,
-  the field 'secret' which contains the clear secret key will
-  be zeroed with random values, the first byte will be 0.
-
-  'nonce' contains the nonce required to decrypt the encrypted
-  secret, if set.
-
-  'serial' is a random number.
-
-  'id' is a string containing the hex values of the CRC32 checksum
-  of the public and secret key.
-
-  Upon creation everything will be filled with random bytes.
-  String fields will contain a string followed by 0 followed
-  by the rest of the pre-filled random bytes. To denote a string
-  field as empty, the first byte will be set to 0.
-
-  There are dynamically calculated attributes as well:
-
-  'checksum' is a 256 bit SHA hash of the public key returned
-  by pcpkey_getchecksum() or pcppubkey_getchecksum().
-
-  'random id' is a random art ascii image returned by
-  pcppubkey_get_art() or pcpkey_get_art(), calculated from
-  the public key.
-
-  If exported to a single file or printed, the structure will
-  be encoded using Z85 encoding.

+/* Bucket expansion has the effect of doubling the number of buckets
+ * and redistributing the items into the new buckets. Ideally the
+ * items will distribute more or less evenly into the new buckets
+ * (the extent to which this is true is a measure of the quality of
+ * the hash function as it applies to the key domain). 
+ * 
+ * With the items distributed into more buckets, the chain length
+ * (item count) in each bucket is reduced. Thus by expanding buckets
+ * the hash keeps a bound on the chain length. This bounded chain 
+ * length is the essence of how a hash provides constant time lookup.
+ * 
+ * The calculation of tbl->ideal_chain_maxlen below deserves some
+ * explanation. First, keep in mind that we're calculating the ideal
+ * maximum chain length based on the *new* (doubled) bucket count.
+ * In fractions this is just n/b (n=number of items,b=new num buckets).
+ * Since the ideal chain length is an integer, we want to calculate 
+ * ceil(n/b). We don't depend on floating point arithmetic in this
+ * hash, so to calculate ceil(n/b) with integers we could write
+ * 
+ *      ceil(n/b) = (n/b) + ((n%b)?1:0)
+ * 
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),
+ * so now we can write this with a bit shift and logical AND:
+ * 
+ *      ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)
